Description.

As shownim the drawings, journal boxes wrhen constructed and arranged inaccord-' ance with the present invention, have a barrel-like body 10.Extended from the upper vsurface thereof and "centrallydisposed'I-isaWearing-pad 11, and extending from the center of the: pad11,'is= a centering' dowel 12. The dowel12, as seen best in Fig. 5 ofthe drawings, rests in an orifice l3sprovidedatherefor in the pillarplate 14. The weightof the" carsan'dthe sills 15 thereof, are directlysupported by the pillar platei'l l andtheipa'd 11. p i

mining cars. The wheels 16 of these cars have hubs 17, which are mountedrotatively on the axles 18. The axles 18 have'journal sections l9thatrest in theboxes having the bodieslO, and in supported relation to therollers 37 mounted therein.

A variation in the arrangement of the track beds requires the use ofwhat are known in thetrade as inside wheels, While other arrangementsrequire the use of what are known as outside Wheels. The insi'dewheelsare'those where the same are disposed'inservice inside of the sills 15'and the pillar plates'll mounted thereon. The outside wheels are thosedisposed outside of said sills and pillar plates.

In all instances the journal boxes are situated directly below saidsills and plates. From this it is obvious that when the axles 1b areprovided with outside wheels,'said axles 'must extend through both endwalls of t-he ournal boxes. -With this end view, the boxes areconstructed with an in tegral; end 21 having an orifice therein, and

a felt packing 22- annularly disposed about said orifice in wipingcontact with the axle 18 to prevent seepage of oil from'the boxes.

The opposite end of the boxes is "closed by a removable plate 23. Theplate 23is provided with a'packing 22 similar'to that above' described.The plate 23 is'held in service relation to the body '10 by bolts 2%,the said plate being provided with radially-extended lugs 25 fitting thelugs 26 provided on'the body 10. This con- 1 struction renders itpossible at any time to replace the plates 23 andthus compensate forwear when thesame are subjected to abrasion by the hubs 17 of the wheels16.

The box'bodies are provided with suspension lugs 27. The lugs 27 aredisposable between 'an'd pierced to correspond with bolt-holes providedin the lugs 28 dependent from the-pillar'plate 14:. Through theperforations in the-lugs 27 and 28 are extended the bolts 29. "Theorifices '30 in the lugs 27 for the bolts 29, are purposelyenlarged-tdpermit a certain amount of movement' of the boxesand'the lugs27 thereof in'service. I

lVhen boxes are thus mounted in service, it isevident that when throughaccident or'otherwise it becomes necessary to remove or reverse'abox,this may beaccomplished by lifting -the body of the car until the dowel12-is'free' of the orifice 13 in the plate 14:, the bolts 29 having beenpreviously removed from engagement with the lugs 27 and 28. It isobvious that the elevation of a car to permit this is slight.

It'is obvious that this arrangement effects a great saving in time whenperforming this operation, for the r'eason'that in former constructions,it has been necessary to remove the plate 1 1 or parts connected theretoby means ofbolts which have extended upward through the sills 15. If thecar requiring repair happened to be filled, the annoyance and loss oftime necessary to the change, is obvious for the reason that the carwould have to be emptied prior to removing the bolts that retained theboxes in position.

The pillar plate 14 is provided at the outer side with a standing linerflange 31. The flange 31 is partially cut away to form an opening 32,whereby provision is made for delivering oil to the passages 33, and

by means of said passages to the roller casing ofthe bearings. Thepassages '33 deliver oil to-channels 34, which channels converge at thecenter of the boxes for delivery to a main channel 35 extending underthe lower half of the boxes and atthe center thereof. e

It is obvious that whatever oil is poured in the passages 33, will flowto the lower portion of the box bodieslO.

If the roller bearings are provided with the wearing casing 36, as shownin the drawings, this casing ispreferably furnished with perforationsin-line with the central plane of the boxes through which the oil willpass to the interior where the rollers 37 I are mounted.

It will be understood that while the easing 36 may be thus provided,this is not essential' to the satisfactory working of the oiling systemfor-the reason that the oil after filling the channel 35 at the bottom.

thereof will overflow and pass by and over the edges of the casing, andthus gain access to the path of the rollers. I It is obvious that whenoil is deposited on the rollers, it will Qbe distributed thereby to thejournal sections 19 of the axles 18, providing a perfect lubrication forthe same. c

In Fig. 4; of the drawings, a modified form of the invention isdisclosed, the modi- Y fication consisting in providing. the box bodies10 with two removable plates 23.

When constructed in this manner, it is obvious that in the-event ofeither of the plates becoming worn by attrition with the hub 17 of theadjacent wheel, the box may be temporarily reversed end for end so thatthe opposite plate will serve to hold the wheelin lineand in serviceposition. Also it will be seen that these plates maybe quickly andreadily renewed whendesired.

In Fig. 5 of the drawings, a further modification; is shown, themodification herein o to e distributed therefrom to the rollers 37 s (7lat 1m.
